With the clone in hand, the two had a decision to make. Since Prasher cut the GFP gene out of the jellyfish genome with restriction digestion enzymes, the clone had extra DNA segments that bookended ...

The axolotl (Ambystoma mexicanum) has extraordinary regenerative abilities—the salamander can regrow lost limbs and repair ...

Humans have been selectively breeding cats and dogs for thousands of years to make more desirable pets. A new startup called the Los Angeles Project aims to speed up that process with genetic ...

fluorescence and red is chlorophyll fluorescence that is seen upon silencing of the GFP gene. (B) C. elegans engineered to express GFP in cell nuclei. Animals on the right have been treated with a ...

In particular, a green-fluorescent protein (GFP) gene was fused with Dpp to produce a single protein product containing both Dpp and GFP domains. This fusion gene was expressed in Dpp mutant flies ...

Knocking in genes allows scientists to study the effects of specific gene variants, to use reporter genes like green fluorescent protein to track gene products in time and space, to probe genome ...
